Abstract

Un mode de réalisation de l'invention concerne un procédé comprenant l'initiation, par un ou plusieurs serveurs d'une plate-forme à bouton de conversation (PTT), d'une session d'appel PTT en réponse à une demande d'initiation de session d'appel PTT de la part d'un premier dispositif client, la réception, par l'un ou les plusieurs serveurs, d'un premier schéma de modulation et de codage (MCS) estimé de la part du premier dispositif client, et la réception, par l'un les ou plusieurs serveurs, d'une première émission conformément à un schéma de codage multimédia (MES) initial de la part du premier dispositif client pendant une volée initiale. Le procédé comprend en outre l'émission, par l'un ou les plusieurs serveurs, d'instructions au premier dispositif client en vue d'utiliser un premier MES différent du MES initial pour une deuxième émission pendant une volée suivante.
